(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A251556 Conjectured values of n which are the minimal cycle representatives of finite cycles in the permutation of the natural numbers defined by A098550. 2
1, 2, 3, 4, 5, 6, 7, 12, 17, 24, 40, 42, 50, 86, 107 (list; graph; refs; listen; history; text; internal format)



At present we do not know for certain that 11, 29, 36, etc. are really missing, since the status of the cycle containing 11 is not known. It appears to be infinite (see A241412).

For other values that are known to be in the sequence see the Havermann link.

A251411 is a subsequence.
